Hello capejoanna2003 I have a dv7 4180ea laptop that overheats and shut down as well common fault, I have hunted hi and low and found a video on youtube that shows how to strip and take out the mother board of the hp laptop in question, you don't need to take the heat sink off of the main board.
this video will show how to get to the fan when you get this far you need to unscrew the 4 screws that hold the fan case together pull the fan assemble away from the heat sink (there is some tape there as well but it does come away) then you will see the build up of lint dust etc clean it all off give it a quick blow then put it all back together.
My Dv7 runs at a breezy 47c under extreme loads.
Hope you are as lucky as me click on the kudos if you like Cheers Redant

I bought my HP Pavilion dv7 at Akihabara, Japan last December, 2011. First I noticed that the my PC gets very hot and the fan is running at its maximum speed every time I use it. I brought this back to the computer store and I explained to them the problem that I observed in this PC. They told me that since this kind of PC performs at high speed, then it naturally gets hot easily. One of their technician even adviced me not to do multi tasking to prevent the CPU from running to maximum capacity. I think this guy does not know what he is saying. Based on the specifications of this computer, HP Pavilion dv7 was designed to perform at high speed and can do multi tasking but here is a technician who says limit the use of my laptop. They did not give any good solution to the problem so I was so disappointed. I bought a laptop fan hoping it can help lower down the temperature of my PC. It did help however the fan is still working at its maximum speed and it is still getting hot. Since I was so helpless and I don't trust anymore those people from the computer store, I tried to figure out what causes my PC to overheat. For my old laptops, I usually clean the fans and ventilations using a vacuum cleaner and it sucks most of the dirts accumulated in my PC. When I tried to clean my new HP Pavilion dv7, I noticed the presence of fine screen installed inside my PC where the vents are located. The first one is located near the CPU and the other two are found just below the 2 hard disk. Since the hole of these screens are too fine, it limits the entry of air to cool down the CPU and the whole PC as well. What I did was to remove these screens and now I observed a very big difference on my PC. The fan now runs at a normal speed and does not overheat anymore. Although, this move is not accepted because the waranty of my PC is void already but I'm still happy because I myself made a solution to this overheating problem. Now I can do multi tasking without any problem on overheating. HP must have to re design their PC to avoid such problems to arise in their next generation PCs. HP can contact me if they need my advice. I will be happy to be of help to the company.

Yep, same problem...overheating to what seems a dangerously high temp. I feel it's a danger to have this machine in my house. The fan runs high and the whole laptop gets hot...In some places it will burn you if you touch it. HP should be sued and this item should be an instant recall.

We have a HP 1150us g7 and like the HP ink cartridges they should don't give their equipment away.
We paid full price for this after our home was broken into and we were cleaned out.
Our HP 1150us g7 runs hot and this is long after some of your purchased your own HPs.
I have been able to do some of the most common repairs on our other PCs however the placement of the COOLING FAN on this HP Laptop is unbelievable.
I won't be replacing this fan, I am sure even a Veteran Safe Cracker could not get into to replace this fan. It requires a near complete taking a part of the entire laptop and only the Good Lord knows if I would ever get it back together. Then like some car recalls you replace the fan with the same kind of fan that failed into a laptop that will clearly have the same issue again and again.

I have a dv7 laptop that is a year and a half old, it was overheating also, getting really hot and shutting itself down daily. I took it apart using the link posted which was very helpful except that it forgot to mention the three screws inside the battery compartment, once you remove them the top cover (palmrest) comes off really easily. The air passages between the heat sink and the fan were clogged just as someone said above, once cleaning it out, the laptop works normally now. Thanks to all who posted the suggestions and take apart pictures they were very helpful.

It appears this in not just HP a number of companies have cut their budgets and the first thing to go is customer satisfaction and help.
A number of us, I could not begin to count how many, have BEEN FAITHFUL SUBSCRIBERS TO SMART COMPUTING Magazine SINCE AT LEAST 1995.
It had the greatest folks on the greatest Q&A forum on the web. This past weekend the company shut it down, no advanced notice or warning it is just gone.
Paid subscribers can access a Homepage to ads and nothing more. Many dear friends and contacts are gone, no way to find them or contact them.
I wrote the editor and stated how many friends and family I sent there just for the wonderful help on the Q&A forum. People were pleasant civil and helpful.
It does not matter, they are going to run ads and nuts to the faithful subscribers over the decades that made the Magazine what it is today, and will never be again, no one is going to renew.
I believe this is more and more the corporate line, sell the merchandise and run.
